GSM or bust for me :) CDMA technology has never been an interest of mine, and I have always been against a phone company that locks down phones as much as Verizon has in the past (and more than likely still does).

Verizon can't lock iPhones or Windows Phones like they do with their feature phones or shitty Android phones (all Android phones are shitty). Also you'd be interested to know that CDMA is superior to GSM, that's why GSM tech 3G or above uses CDMA as the underlying transmission protocol.

Plus all the new top-tier CDMA phones also have a sim card slot to use on GSM networks.
